Several years ago, I wrote an article on using Elmer to solve complicated physics problems. Elmer has progressed quite a bit since then, so I thought it would be worth taking a fresh look at this ...

Heun functions, which generalise the well‐known hypergeometric functions, are solutions to the Heun differential equation – a second‐order linear differential equation with four regular singular ...

High levels of system functionality reached the analog-IC world many years ago. After all, why just have an A/D converter when you can instead have an IC with other needed functions such as ...
